Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a non-contact type automatic ticket gate (hereinafter referred to as an automatic ticket gate). The automatic ticket gate G has a door 1 for opening and closing a ticket gate passage P on a side surface of a housing H, and a display unit 2 for displaying a passable direction to a user is provided on a front surface of the housing H. Has been. Further, a communication area 3 for transmitting and receiving data to and from the card C carried by the user by wireless communication is provided on the upper part of the front of the housing H. In this communication area 3, antennas a connected to a transmitter, which will be described later, are exposed.

Numerals S1, S2 ... Are photoelectric type human detectors for detecting a user's entry into the ticket gate passage P, exit from the ticket gate passage P, or passage, and the side surface of the casing H and the arm 4 are detected. Installed on. A speaker 5 for broadcasting a predetermined guide to the user is attached to the side surface of the housing H.

Reference numeral 6 denotes a controller for controlling the operation of the automatic ticket gate G, which is configured using a microcomputer. The controller 6 is connected to a transmitter T that transmits and receives data to and from the card C, and a detector described later.

The transmitter T transmits a transmission signal modulated with data such as the station name and the date of the day from the automatic ticket gate G to the card C via the antenna a, as in the known non-contact automatic ticket gate. And has a function of demodulating data of the boarding section and the like sent from the card C.

In FIG. 1, A is a photoelectric holding object detector, which is constructed so that the user can detect the state where the card C is held over the antenna a. The holding object detector A may be a well-known ultrasonic type or pyroelectric type.

FIG. 2 is a block diagram showing the electrical construction of this embodiment. Explaining from the automatic ticket gate G side, in addition to the holding object detector A being connected to the controller 6,
A door drive unit 7 for opening and closing the door 1, a lamp drive unit 8 for lighting the lamps L1, L2 provided on the arm 4, and a sensor amplifier 9 for inputting signals from the human detectors S1, S2. Has been done. It should be noted that the controller 6 is also connected to an audio unit or the like for driving the speaker 5, but it is omitted here.

The card C, similar to a normal IC card having a wireless communication function, has a receiving antenna 10a and a reflecting antenna for phase-modulating the data sent from the card C to the automatic ticket gate G to generate a reflected signal. 10b, a receiving unit 11 that processes a signal received by the receiving antenna 10a, a CPU 12 that stores data from the automatic ticket gate G and a memory that stores data (card data) such as a boarding section, and a card A phase modulator 13 for modulating the subcarrier from the CPU 12 with data to modulate the phase of the reflected signal, and a battery E for driving the card C are provided.

In the card C having the above structure, the antenna a
When the transmission signal transmitted from the receiving antenna 10a is received, the transmission data from the automatic ticket gate G side is extracted by the receiving unit 11 including a detection circuit, a demodulation circuit, etc., and the CPU 1
2 memory.

The CPU 12 controls the frequency of the main carrier (eg, 2.45 GH) when the transmission signal of the automatic ticket gate G is generated.
z) A subcarrier of, for example, 500 KHz, which is sufficiently lower than that of z), is generated and output to a multiplication circuit (not shown) of the phase modulator 13 and card data (digital signal) to be transmitted to the automatic ticket gate G is generated. The signal is output to a multiplication circuit (not shown) of the phase modulation unit 13. Therefore, a signal obtained by modulating the subcarrier with the card data is generated from the multiplication circuit.

The generated signal passes through the phase modulation circuit (not shown) of the phase modulation section 13 and the reflection antenna 10b.
Power is supplied to Therefore, when the main carrier that is transmitted from the antenna a of the transmitter T in a time-division manner and hits the reflecting antenna 10b and is reflected, the phase is just modulated with the card data.

When the antenna a of the transmitter T receives the reflection signal reflected by the reflection antenna 10b, the reception circuit (not shown) performs detection processing, filtering processing, and amplification processing to extract data from the card C side. Then, the extracted card data is sent to the controller 6 of the automatic ticket gate main body G.
To be used for the automatic ticket gate calculation process.

Next, the control operation of the automatic ticket gate will be described with reference to the flowchart of FIG.

First, when the user tries to enter the ticket gate passage P using the automatic ticket gate, it is detected by the human detector S1 provided at the entrance side of the ticket gate passage P (Yes at step 100. , Step S.). Next, when trying to hold the card C over the antenna a, the card C
It is detected by the holding object detector A (Yes at S102). In this state, when the data is smoothly transferred between the card C and the automatic ticket gate G and the arithmetic processing for the ticket gate processing is performed (Yes at Step 104), the result of the arithmetic processing permits the entrance and exit. When it is possible, the door 1 is opened (when the automatic ticket gate G is a normally open type, it remains the same) (S10
6, S110), the automatic ticket gate processing by the card C is performed.

By the way, when data is not smoothly transferred between the card C and the automatic ticket gate G even though the holding object detector A detects the holding state of the card C, Alternatively, when the card C is determined to be an invalid card (No in S104), the door 1 is closed and the user and the staff are informed that the passage of the lamp L1 is blocked (S110).

The user advances to the central portion of the ticket gate P, which is the human detector S4 provided at the center of the ticket gate P.
Since the door 1 is closed before being detected in ~ S7, the user can know that the passage through the ticket gate passage P is blocked at a position far from the door 1, and therefore the door 1 is erroneously detected. It is possible to prevent the collision.

The provision of the lamps L1 and L2 or the speaker 5 for indicating passage prevention is particularly effective in the case where the automatic ticket gate G is provided in a small station and the door 1 is omitted. In the present invention, the term "door control means for closing the door" also includes notifying the user via the lamps L1 and L2 or the speaker 5 that the ticket gate passage P cannot be passed. There is.

[0025]

The non-contact type automatic ticket gate according to the present invention has a human detecting means provided on the entrance side of the ticket gate passage of the main body of the non-contact automatic ticket gate, and a detection for detecting a holding object held up by the transmitter. Means and the human detecting means detect a user, the detecting means detects a holding object, and is provided in the main body of the non-contact type automatic ticket gate when the transmitter does not communicate. Since it has a door control means for closing the existing door, the user can know that the passage through the ticket gate passage was blocked at a position far away from the door, and the user can accidentally collide with the door.
